Detailed Description

This proxy transposes the source model.

Since
5.13

\inmodule QtCore

This model will make the rows of the source model become columns of the proxy model and vice-versa.

If the model is a tree, the parents will be transposed as well. For example, if an index in the source model had parent index(2,0), it will have parent index(0,2) in the proxy.
